Usage description of hydraulic hose
Hydraulic hose used in hydraulic support, oil field drilling, mine is suitable for engineering construction, lifting, transportation, metallurgy forging press, mining equipment, vessels, injection molding machinery, agricultural machinery, all kinds of machine tools and various industrial departments mechanization in hydraulic system, automatic transmission has a certain pressure and temperature of the oil base fluid, water-based liquids, gases and liquids such as transmission.
Hydraulic hose is also known as hydraulic tubing, hydraulic hose, high pressure hose, hydraulic hose, steel wire high pressure hose, steel wire braided hose steel wire wound hose, generally divided into steel wire braided hydraulic hose and steel wire wound hydraulic hose. Hydraulic hose is mainly composed of liquid resistant inner rubber layer, middle rubber layer, 2 or 4 or 6 layers of steel wire winding reinforcement layer, outer rubber layer, the inner rubber layer has the effect of making the transmission medium under pressure, protecting the steel wire from erosion, the outer rubber layer protects the steel wire from damage, the steel wire layer is the skeleton material plays an enhanced role.
Hydraulic oil is the energy transmission medium of hydraulic station, and the transmission of medium requires high pressure tubing, so the quality of hydraulic hose may affect the work of the whole hydraulic system. Hydraulic hose pressure, *** standard requirements test pressure is 2 times the working pressure, *** pressure is generally 3-4 times the working pressure is qualified; Simple appearance method: look at the appearance to see the brightness of the section, the high brightness is the top grade, and the nail pinching its gelatinous elasticity is good.
